FASTENING FOR CORRUGATED METAL SH EETS.

SPECIFICATION forming part of Letters Patent No. 297,862, dated April29, 1884. 7

Application filed February 29, 1884. (No model.)

To 60% whom it may concern.-

Be it known that I, J OHN SMITH, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Fastenings forCorrugated Metal Sheets; and I hereby do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in the manufacture of corrugatedmetal sheets, and in securing them in place upon buildings.

It consists of using hook-shaped fastenings instead of nails, and,further, of stamping depressions in the edge of the sheets, whichdepressions are adapted to fit over hooks previously attached to thetimbers of a building, so that said hooks shall not prevent theoverlapping sheets making a snug joint with the sheet underlying it.

Figure 1 represents a plan view of two corrugated metal sheets, oneoverlapping the other, and having a corner cut away, each being held inplace upon a piece of timber by my improved fastenings. Fig. 2 shows inperspective one hook properly fixed toa piece of sheeting or siding withone corner of a metal sheet inserted beneath the hook end thereof. Fig.3 is an end view, showing how two sheets are joined sidewise and held inposition bymeans of acurved fastening. Fig. 4 shows the end of acorrugated metal sheet having the stamped depressions for the receptionof that part of the fastening beneath which the edge of the initial orlower sheet is inserted.

Referring again to the drawings, A represents a fastening, constructedpreferably of wrought-iron, having one end flattened and suitable holespunched therein for attaching it to the timber of a building by means ofscrews or nails, and the other turned to form a short hook.

Sheets of metal are prepared by running them through acorrugating-machine having suitable dies upon the rolls that form the dein the position shown, the indentations or def pressions B fittingwithin the short hooked ends of the fasteners A. As before stated, theseindentations are to make room for the fasteners, so that the overlappingsheet D will not be held away from the sheet E. Any number of sheets maybe thus applied, and their straight edges are secured by means of hooksO, curved to fit the corrugations, and

fastened to the timbers, as before described.

They may be placed any suitable distance from each other, and inapplying them, a line of sheets having been run up the building, thehooks C are placed so that the curved ends thereof fit across theoutside convex edge of the sheets, and upon applying another course ofsheets-the edges of such course lap over those previously laid, and areheld in such position by the short hooks upon the curved end of sidefastenings, C.

By the application of my improved metal sheets, leaky nail-holes andnails are entirely dispensed with, and the sheets are free to expand orcontract with the varying temperatures and conditions in which it may beplaced. When the. under side of the sheets become rusty or corroded,they may easily be taken off, painted, and reversed. With a common sheetroof or siding or an inside ceiling this cannot be accomplished.

The fastenings can be applied to iron rafters of buildings by means ofbolts or rivets. They may also be used in fastening slate.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 7 1. A corrugated metal sheet having depressions orindentations B stamped or rolled upon one edge or side, suchindentations being situated within the longitudinal concavities of thesheet, substantially as shown and described.
